Oil Reservoir
The A-4000-145 Oil Reservoir (see Figure 11) provides
a means of identifying excess oil pumping (compressor
maintenance) as well as water entrainment (air dryer
maintenance). If either occurs, replacement of the oil
removal elements is required. The oil reservoir also
provides a means of collecting the coalesced oil for
proper disposal.
Oil Removal Filters
The combination of coalescing and activated charcoal
filters (see Figure 12) in series removes both oil
aerosols and vapors to provide clean, oil-free air for
pneumatic control systems. These filters have a
maximum input pressure rating of 150 psig (1,050 kPa)
and an upper temperature limit of 125°F (52°C).
